The teenage years have always been tough—but digital technology has raised the dangers of the social battlefield to a whole new level. This ABC News program reports on how cell phones, digital cameras, and personal Web sites encourage and amplify the frequent cruelty of teen behavior.

The program also looks at the difficulties parents face in monitoring what kids do on the Internet. (40 minutes)
